Reorganize Contributing.rst and fix a few typos

This document is shown when creating pull requests and referenced
from a number of other code-related discussions, so putting the
"contributing code" section first probably makes more sense
(particularly with a TOC).

-You can help without coding
-===========================
-DFHack is a software project, but there's a lot more to it than programming.
-If you're not comfortable pregramming, you can help by:
-
-* reporting bugs and incomplete documentation,
-* improving the documentation,
-* finding third-party scripts to add,
-* writing tutorials for newbies
-
-All those things are crucial, and all under-represented.  So if that's
-your thing, the rest of this document is about contributing code - go get started!
-
-Documentation Standards
-=======================
-Whether you're adding new code or just fixing old documentation (and there's plenty),
-there are a few important standards for completeness and consistent style.  Treat
-this section as a guide rather than iron law, match the surrounding text, and you'll
-be fine.
-
-Every script, plugin, or command should be documented.  This is an active project,
-and the best place to put this documentation might change.  For now, it's usually
-either ``docs/Scripts.rst`` or ``docs/Plugins.rst``.
-
-Where the heading for a section is also the name of a command, the spelling
-and case should exactly match the command to enter in the DFHack command line.
-
-Try to keep lines within 80-100 characters, so it's readable in plain text -
-Sphinx (our documentation system) will make sure paragraphs flow.
-
-If there aren't many options or examples to show, they can go in a paragraph of
-text.  Use double-backticks to put commands in monospaced font, like this::
-
-    You can use ``cleanall scattered x`` to dump tattered or abandoned items.
-
-If the command takes more than three arguments, format the list as a table
-called Options.  The table *only* lists arguments, not full commands.
-Input values are specified in angle brackets.  Example::
-
-    Options:
-    
-    :arg1:          A simple argument.
-    :arg2 <input>:  Does something based on the input value.
-    :Very long argument:
-                    Is very specific.
-
-To demonstrate usage - useful mainly when the syntax is complicated, list the
-full command with arguments in monospaced font, then indent the next line and
-describe the effect::
-
-    ``resume all``
-            Resumes all suspended constructions.
-
-If it would be helpful to mention another DFHack command, don't just type the
-name - add a hyperlink!  Specify the link target in backticks, and it will be
-replaced with the corresponding title and linked:  eg ```plugins/autolabor```
-=> `plugins/autolabor`.  Link targets should be the path to the file
-described (without file extension), and placed above the heading of that
-section like this::
-
-    .. _plugins/autolabor:
-    
-    autolabor
-    =========
-
-Add link targets if you need them, but otherwise plain headings are preferred.
